FOLDING TENT-FRAME. 1

Specification of Letters Patent. Patented June 10,1915} Application filed February 14, 1918. Serial No. 217,284.

To all whom it may concern: 7

Be it known that 1, MICHAEL OSTROSKI, a subject of the King of Great Britain, residing at Ooniston, in the Province of Ontario, Dominion of Canada, have invented a new and useful Folding Tent-Frame; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

The present invention rel-ates to a folding tent frame, and has for its object to provide a device of this character which embodies novel features of construction wherebyit can be compactly folded when not in use,

but which can be quickly set up in operative position and will then provide a substantial support for a tent.

With this and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is an end view of a tent frame constructed in accordance with the invention, the tent being indicated by dotted lines.

Fig. 2 is an enlarged side elevation of the ridge pole, showing the same by full lines as extended and by dotted lines as folded, portions being broken away.

Fig. 3 is a detail view of the upper end of one of the end frames.

Figs. 4, 5 and 6 are detail views of a triangular block which may be fitted in the crotch at the upper end of the end frame.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, which illustrate one embodiment of the invention, the numeral 1 designates the ridge pole, and 2 an end frame, one of which is provided for the support of each end of the ridge pole. By reference to Fig. 2 it will be observed that the ridge pole is formed in two sections 1 which are hingedly connected at their middle portion, as indicated at 3, so that they can be folded against each other and packed in a comparatively small amount of space when the ridge pole is not in use. As indicated on the drawlng, the abutting ends of the ridge pole sections l may have metal cap pieces 4: applied thereto for the purpose of protecting the wood against wear at this point and insuring a straight ridge pole when the sections 1 thereof are inverted and swung into alinement with each other.

Each of the end frames 2 includes two props 2 which overlap and are pivotally connected at their upper ends, as indicated at 5. These props 2 are adapted to be folded against each other when the device is not in use, although when setting up the frame in operative position the lower ends of the props are swung apart and the outwardly. curved prongs6 at theextremities thereof embedded in the ground. The outward curvature of these prongs 6 enables them to provide a firm anchor for the props, since it is difficult to force-them downwardly or laterally through the earth, and the two props are connected to each other so that neither of them can swing downwardly to permit of thecurved prongs entering more deeply into the earth along the line of least "resistance. u

The upper ends of the props 2 extend beyond the pivotal connection 5, thereby providing a crotch within which a triangular block 7 may be fitted. One of the angular corners of the block 7 fits accurately in the crotch, the sides thereof being rabbeted upon opposite edges thereof, as indicated at 8, to receive the edges of the respective prop members, thereby providing an interlocking relation which results in holding the block firmly in position. The upper edge of each of the blocks 7 is notched at 9 to receive the respective end of the ridge pole 1, and the ends of the ridge pole may be notched at their lower edges, as indicated at 10 to provide for a positive engagement with the blocks and hold the ridge pole against longitudinal movement. A tent of the usual type may be supported upon this frame, as indicated by Fig. 1, and it will be obvious that the ridge pole is held firmly in position within the notched seats 9 of the block 7 so that it is impossible for the ridge pole to swing or tilt to either side under the action of the stretched tent fabric. A rigid tent support is thus provided when the device is inverted and set up for use, although it will be obvious that the frame can be collapsed and packed in a small amount of space when not in use.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

l. A folding tent frame including a ridge pole, end frames formed of props which are pivotally connected at their upper ends and adapted to be swung apart at their lower ends, the upper ends of the props being 8X tended beyond the pivotal connection to provide crotches when the props are swung apart, and triangular blocks fitted in the crotches and recessed at their edges to interlock with the sides of the crotch, said blocks being formed with seats for the reception 0 the ridge pole.

2. A folding tent frame including a ridge pole, end frames formed of props which overlap and are pivotally connected at their upper ends, the lower ends of the props being adapted to be swung apart, While the upper ends of the props are extended beyond the pivotal connection to provide a'crotch,

and triangular blocks fitted in the crotches and having the sides thereof rabbeted at opposite edges to receive the sides of the crotch, the blocks being also provided with notched seats for the reception of the ridge pole.

3. A folding tent frame including a ridge pole, end frames formed of props pivotally connected at their upper ends and terminating at their lower ends in outwardly curved prongs adapted to be embedded in the earth when the props are swung apart, the upper ends of the props being extended beyond the pivotal connection thereof to provide a crotch when the props are swung apart, and triangular blocks fitted removably within the crotches and formed with notched seats for the reception of the ridge pole.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
